I just did a quick read on it on it. “Work” is the application of force over time in the direction the object is moving. Pushing a shopping cart for example is work, because you have to constantly apply force to it.
From what I’ve read, it seems that magnetic force doesn’t do work because it doesn’t apply force in the direction the object moves. Magnetic force only “deflects” or changes the direction of an object with an existing velocity. It’s only a deflection because the force applied is always perpendicular to the direction of the velocity.
To use the previous shopping cart example, picture a shopping cart that already has a forward velocity that passes a magnet. The magnet only applies a force to the side of the cart towards the magnet. This doesn’t push the cart itself, but changes the direction of its velocity towards the magnet.
I’ve actually never tried brave search. Which is kinda funny because I started using DDG when brave came out and it was the default search engine.
What do you mean by slow though? Like just the webpage loading or the time it takes you to get good results? I’ve never noticed any load time, but I’ve always had a few tweaked content blockers running and that may affect my perspective.
